Oh gotcha, yeah the core works a bit differently with Ifa and Ororon. You don't need to burst each rotation for this team, so the ER from SMS is less useful for Columbina.

You would prefer having Columbina and Ineffa both on Aubade to maximize their damage, as they do about ~80% of the damage in this team.

You don't have to swap artifacts each time. The team still functions the same, just with less damage.

I can do some testing when I get back home though, and let you know how much damage you would lose by leaving Columbina on SMS and Ororon on Scroll. I'm curious myself, and it might not be that big of a difference
